Net asset value, premium and discount, and the Grayscale trust

Net asset value is what a product's holdings are worth, divided by the number of shares outstanding. Market price is what the shares actually change hands for on an exchange. The two are different numbers produced by different processes, and the gap between them, expressed as a percentage, is the premium or the discount. A persistent gap is almost always a statement about the wrapper's plumbing rather than about the asset inside it.

How the daily value is struck

Net asset value is computed once per business day by the administrator. It takes the quantity of the asset held, applies a reference price, subtracts accrued liabilities including the unpaid portion of the sponsor fee, and divides by shares outstanding. The reference price is not a single exchange print. It is usually a composite calculated over a defined window, drawn from several venues and weighted by volume, with rules for excluding stale or outlying prints. Products in the same market can use different reference rates and different windows, which is enough to produce small, permanent differences between their published values on the same day.

Two timing facts follow. The published value is a snapshot at the valuation window, while the asset keeps trading afterwards, so a share bought late in the session is priced against a stale reference. And the share only trades while the exchange is open, whereas the underlying trades continuously, so the value of the holdings moves overnight while the share cannot. Intraday, many sponsors also publish an indicative value updated frequently, which is closer to what a market maker is actually quoting against.

The arithmetic of premium and discount

The premium or discount is the market price minus net asset value, divided by net asset value. Positive is a premium; negative is a discount. In a product with a functioning primary market, the number is normally small and mean-reverting, because the creation and redemption process described earlier gives professional firms a profit motive to close it. What makes the number worth watching is the shape of its distribution rather than any single reading: a product that oscillates within a narrow band is behaving as designed, while one that sits on one side for weeks is telling a story about constraint.

The usual causes of a sustained gap are mechanical. Creations may be suspended, so new demand cannot be supplied. Redemptions may be impossible by design, so excess supply cannot be withdrawn. The authorized participant roster may be too short, or the cost of hedging in the underlying may exceed the size of the gap. A product may be listed in a market whose hours do not overlap the deepest trading in the asset, so the share opens against yesterday's information. In each case the gap is the price of a plumbing constraint, and it disappears when the constraint does.

• Creations suspended or capped pushes toward a premium, and reopening issuance resolves it.
• An absent redemption program pushes toward a discount, and only a structural change that restores redemption resolves it.
• Thin underlying liquidity or costly hedging widens the band in both directions, and deeper markets narrow it.
• An exchange closed while the asset keeps trading produces a transient gap that the next open removes.
• Few or concentrated quoting firms widen the band until more of them compete.

The Grayscale trust as the standard illustration

The clearest demonstration is the bitcoin trust run by Grayscale, which existed for years as a closed-ended vehicle before it became an exchange-traded fund. Its structure was a grantor trust whose shares were first sold privately to eligible investors, who delivered assets or cash and received shares subject to a holding period before those shares could be resold in the public quotation market. Crucially, the trust operated an ongoing creation channel but no redemption channel; a redemption program had been discontinued years earlier following a regulatory objection, and reinstating it required regulatory permission the sponsor did not have.

The result was a one-way valve, and the price behaved exactly as a one-way valve implies. When demand for exposure through a brokerage account exceeded the supply of unlocked shares, the shares traded at a substantial premium, which in turn made the private creation route profitable: deliver assets, wait out the holding period, sell into the premium. That trade attracted leveraged participants and became a crowded position. When demand reversed and the pipeline of newly unlocked shares kept arriving, there was no mechanism to shrink the share count, and the trust moved to a deep and persistent discount that lasted through 2022 and into 2023, at its widest reaching a level measured in tens of percent. Holders of the shares who wished to exit had only one route, which was to sell to another buyer at whatever the market offered.

The discount also transmitted stress into the wider market. Firms that had accumulated shares expecting a premium found themselves holding an illiquid asset marked well below the value of the underlying, and some of those positions were pledged as collateral. The unwinding of that trade was one of the strands in the 2022 credit failures, alongside the collapse of Terra and the failures of Celsius, Three Arrows and FTX. When the vehicle was converted to an exchange-traded fund in January 2024 and a redemption path opened, the discount closed toward zero within days. Nothing about bitcoin changed on those days; the plumbing changed.

How to read the number without over-reading it

A discount is not a claim that the underlying asset is mispriced, and it is not a free spread. It is compensation for the constraint that prevents the gap from closing, and capturing it requires the constraint to end at a knowable time. When the constraint is legal or regulatory, the timing is a matter of judgment about process, not arithmetic, and the discount can widen further while the process runs. Symmetrically, a premium is not evidence of enthusiasm for the asset; it usually means the supply of shares is capped while demand through that particular channel is not.

The useful comparison is across wrappers on the same asset. Two products holding the same thing, with different fees, different reference rates and different primary-market arrangements, will show different gaps, and the differences isolate the wrapper. Aggregate context sits in ETP coins held and ETP share of supply, while the value of the wrapper channel overall is ETP assets under management. The ETP pages hold these series, and the next page in this track takes apart the fee that sits between the share and the asset.
